Seafood business development

MatureDevelopment is active in the global seafood industry. Global clients request for technology, business development and scale-up interim management.

Aquaculture has grown in volume and in complexity globally in the last several decades. While aquaculture has a centuries-long history as a source of food for households in Asia and Africa, the most dramatic change in more recent years has been the development of aquaculture businesses into complex multinational industries. These industries operate on national and international levels, like the Americas, Europe, Middle East, Southern Asia, North Asia, South East Asia and Australasia. Competition is global.









Development of efficient and viable businesses requires careful evaluation and thorough planning for the new business. Taking into account global aspects outside the core of aquaculture; logistics, politics, fish/shrimp diseases, health improvement, human pandemics,…

Innovation and change in aquaculture; Global competitiveness in a world turned upside down.

Innovations are necessary to fulfil changing societal needs, support sustainable development and create societal resilience.

Our purposeful, systematic innovation begins with the analysis of the opportunities in the industry. It begins with thinking through the sources of innovative opportunities. In different areas of the industry, different sources will have different importance at different times.

All the sources of innovative opportunity in Nutrition & Health in aquaculture is systematically analysed and systematically studied by the professionals. The search is organized on a regular, systematic basis through our strong network in the industry and R&D organizations.


Innovation is to go out to look, to ask, to listen, to discuss. Our innovators use both the right side and the left side of their brains. They look at figures, and they look at people. They work out analytically what the innovation has to be to satisfy an opportunity in aquaculture. And then they go out and look at the customers, the users, to see what their expectations, their values, their needs are, using our BlueGreen Network.

Our innovation, to be effective, has to be simple and it has to be focused. It should do only one thing, otherwise, it confuses. If it is not simple, it won’t work. Everything new runs into trouble; if complicated, it cannot be fixed. All effective innovations are breathtakingly simple. Indeed, the greatest praise an innovation can receive is for people to say: “This is obvious. Why didn’t I think of it?”

The innovation that creates new uses and new markets should be directed toward a specific, clear, designed application. It should be focused on a specific need that it satisfies, on a specific end result that it produces. Grandiose ideas plans that aim at “revolutionizing the aquaculture industry,” are unlikely to work.

We don’t try to innovate for the future. We innovate for the present! To succeed, our innovators must build on their strengths. Our successful innovators look at opportunities over a wide range. But then they ask, “Which of these opportunities fits me, this industry, fits this company, puts to work what we are good at and have shown in our critical objective tests in farms, capacity for in performance?”


Information Technology in Aquaculture Management

The enormous increase of aquaculture production, global competition and disease control demands instrumentation and process control. At company and industry levels.

The importance of which stems from the close correlation between the environmental conditions, water quality, waste management and factors affecting aquaculture production such as health, feed utilization, feed conversion rate, fish growth rate, water quality, waste management are complex. Information is not only important to fulfil today’s tasks and business processes, information is every day converted into knowledge to support decisions.












The dynamic nature of the production process and the high risk involved in making an inappropriate decision, the quality of the data and its timely availability are of prime importance. Data management is a vital task for aquaculture management.

Stakeholder involvement in aquaculture is a powerful parameter for competitive advancement of the industry. Our platforms like BlueGreen Network  adds mature development in the seafood industry globally.

Continuous education in the dynamic environment of aquaculture is essential. We developed the blended education platform: BlueGreen Masters.

This unique learning experience means all study materials are online, so employees and employers can study with a laptop, smartphone or tablet – at home, at work or even while travelling. Regional courses are added to experience activities under the supervision of professionals.



Research & Development, proving of Functional Feed Additives for business improvement.

Gut microbiota composition, ecological communities of commensal, symbiotic and pathogenic microorganisms, strongly affects the health status of an organism. Recently, extensive researches have been conducted to shift gut microbiota towards an ideal composition for improvement of fish or shrimp health.

Dietary administrations of various probiotics (bacteria), prebiotics (feed additives) and their combination (synbiotics) have been practised for this purpose.

Prebiotics are non-digestible material for fish or shrimp but metabolizable by gut microbiota therefore, dietary prebiotic supplementation, functional feed additives, are used to increase gut beneficial bacteria populations. A variety of prebiotics have been studied for their beneficial effects in human and domestic animals suggesting that each bacterium potentiates to metabolize certain prebiotics.

Numerous studies also by our professionals, showed beneficial effects of prebiotics on growth performance, stress resistance, immune stimulation and disease resistance.


In this domain MatureDevelopment is testing, proving, functional feed additives/biostimulants in Mexican, European and aquaculture farms in Thailand.

Gabriel is a safety and security management professional in The Netherlands. He got inspired by conversations with Paul VAN DER HEIJDEN about aquaculture, wondering how safety and security can be further implemented in this industry. During his studies he learned about the very wide subject of safety and security, however, the conversations added a different perspective on the variety of uses this discipline can have. Safety and security are important for everyone and can be found in different views in every industry. As wide as it is, it varies from crisis management in companies to occupational health and safety in organisations. The reason why he studied safety and security management is that one of his greatest beliefs is to help other people. Not only would he be able to support people around the world with working on food security in the aquaculture industry but it would also provide a more sustainable way to produce food. 

On a personal level, he is interested in change management and to implement when asked for in the aquaculture industry. Another aspect that he would like to add to the industry is to improve quality inside organisations, which would start off by a scan of the organisation. The final goal of the scan is to research the culture of organisations. Both the quality in the production process and the attitude of the management and leadership towards safety are aspects that he has researched in projects. His interests are wide and the opportunity to include his passion for safety and security in them motivates him to explore and support all kinds of seafood industries.
